Crazy Far: How To Get People Into Deep Space - Tim Folger

Some people plan their international vacations for months, but for a very specific NASA mission, it might take centuries to plan. Tim Folger tells Boyd that scientists are starting to think of ways for humans to venture out into the deeper recesses of the universe. The trick, however, is finding a way to power a humungous space ship that can take humans "Crazy Far". Folger's story is in the January 2013 issue of National Geographic magazine.
